Study of the Residue Control Based on Feature-Model

By the criterion of least square variance, the Feature-Model of the Multi-Order systems with pure delay unit is established by calculating the system´s inputting and outputting data. According to the model´s feature, the algorithm is proposed to estimate residual error with the outputting data of the system and Feature-Model, and then residue control value as well as suitable compensating time is obtained to compensate the output for getting the expectant control effects. Simulation shows this algorithm can get better output and compensate the outer disturbance as soon as possible.
